Turmeric (Curcuma longa L.) is well known for its medicinal value, its cultivation is hindered by several diseases viz., leaf spot, anthracnose and rhizome rot. These diseases are managed by using the fungicides, which leads to development of resistant strains besides the environmental pollution and also the residue problem on final produce. Host resistance seems to be most promising means of disease management. Therefore, field screening trial was planned and conductd in Konkan region of Maharashtra at Asond Block, AICRP on Spices, DBSKKV, Dapoli for three years (2015-16, 2016-17 & 2017-18) to identify the disease resistant sources against Colletotrichum leaf spot and Pythium rhizome rot with high yield potential. Three years average data revealed that, out of 30 turmeric varieties screened, 29 were found moderately resistant (MR) and only one variety Kanti was susceptible (S) to Colletotrichum leaf spot. But, on the yield basis amongst all varieties, four varieties viz., Krishna, Sudharsana, Narendra Haldi and Pratibha performed well. Minimum leaf spot intensity was recorded in Pratibha (11.69%), Sudharsana (12.99%), Krishna (13.23%) and NarendraHaldi (13.82%) with high yield of 17.66kg/plot, 18.86kg/plot, 19.46kg/plot and 18.10kg/plot, respectively. Whereas, for rhizome rot, the varieties Pratibha,Sudharsana and NarendraHaldi were tolerant (T) and only one variety Krishna was found moderately resistant (MR). It is concluded from present study that, Krishna, Sudharsana, Narendra Haldi and Pratibha, which may be recommended to farmers for cultivation in Konkan region of Maharashtra.
